CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 336,875, dated February23, 1886 Application filed Sertembvr 19, 1885. Serial No. 177,582. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN A. TURLEY, of Gog Hill, in the county of McMinnand State of Tennessee, have invented certain new and usefulImprovements in Oar-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being. had to the accompanyingdrawings, which form a part of this specification, and in which- Figurelis a longitudinal vertical sectional view of two drawheads of myimproved carcoupling, showing them in the act of coupling. Fig. 2 is afront view of one of the drawheads. Fig. 3 is a side view of adraw-head, and Fig. 4 is a perspective detail view of the slide withinthe draw-head.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of automatic car-couplings inwhich a common pin and link are used in the coupling, the pin beingsupported during the act of coupling by a slide which is forced back bythe opposite draw-head, releasing the pin and consummating the coupling;and it consistsin theimproved construct-ion and combination of parts ofthe same, as'hereinafter more fully described and claimed.

In the accompanying drawings, the letters A A indicate the draw-heads,which are constructed and secured to the cars in the usual manner, thedraw-heads having the recesses B for the reception of the links, and thevertical perforations G for the reception of the pins D. The draw-headsare preferably formed with enlargements E at the perforations for thereception of the pins, as shown at F, for the purpose of supporting thepins in a vertical position when drawn up prior to coupling. The slidesG, which slide in the recesses of the draw-heads, are formed by a platebent to form an upper horizontal portion, H, a downwardly inclinedportion, 1, having a downwardly-turned lip, J, at its end, and anupwardly-bent doubled portion, K, formed by doubling the plate to formthe horizontal and the inclined portion, and thereupon bent upward. Thehorizontal portion and the inclined portion of the slide are providedwith perforations L, which register, and which register with thevertical perforations in the top and bottom of the draw-head, the slidefitting within the recessin the draw-head and sliding in the same, theoutward movement of the slide being limited by the downwardlyprojectinglip of theinclined portion, which bears against a lug, M, projectingfrom the bottom of the recess. of the draw-head. The upwardly-bentdoubled portion fits in a correspondingly-shaped recess, N, in the faceof the draw-head, and a recess or niche, O, is formed in this recess,extending to the upper end of the same and beyond it, so that the pointof a coupling-pin may be inserted between the upwardly-beut portion andthe face of the draw-head, for the purpose of prying the slide outward,setting the slide for supporting the pin ready for coupling.

The draw-head may be provided with a transverse perforation, P, throughwhich a pin may be inserted, serving to keep the link in a horizontalposition, bearing against the upper side of the inner end of the samewhen a loose coupling has to be made with another car. It will now beseen that when coupling has to take place the slide may be drawn out bymeans of the pin,which is inserted into the recess or niche, prying theupwardly-projecting portion of the slide out of its recess, and theslide will now 'have its perforations drawn forward of the perforationsin the top and bottom of the draw-head, so that the pin inserted throughthe upper perforation will be prevented from dropping through and willbe held upright by the enlargement around the perforation. WVhen now thedraw-heads come in contact with each other, the slide will be pushed inand the perforations will register, so that the pin will be allowed todrop down and engage the link, which at this time has entered thedraw-head.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. The combination, with apin-supporting slide having an upwardly-projecting lip, of a draw-headhaving a recess in its face for the reception of the lip, and having arecess or niche extending beyond the upper edge of the recess for theinsertion of a pin for prying the lip out of the recess, as and for thepurpose shown andset forth.

2. The combination ofa'draw-head having the usual recess and the usualperforations for the pin, a slide sliding in the recess and having ahorizontal portion and a downwardlyinclined portion, and having anupwardlyprojecting lip at its outer end and perforations in thehorizontal'portion and in the inclined portion, and a common couplingpin and link, as and for the purpose shown and set forth.

3. The combination ofa draw-head having the usual recess andperforation, and having a recess in its face formed with a niche orgroove extending beyond its upper edge, a slide in the recess,consisting of a horizontal portion and a downwardly-inclined portionhaving adownwardly-bent lip at its inner end, and of an upwardly-bentdouble portion resting in the recess, the inclined and the horizontalportion having perforations registering when the slide is in with theperforations in the draw-head, a pin or lug projecting from the bottomof the recess in the draw-head and limiting the play of the slidebearing against the downwardly-bent lip, and a common coupling link andpin, asand for the purpose shown and at right angles to said horizontalportion,

a downwardly-inclined part having an aperture registering with theperforation in the upper horizontal part, and a downwardlyprojecting lipat the outer end of the inclined part of the plate, substantially as andfor the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoafiixcd my signature in presence of two witnesses.

JOHN ATLAS TURLEY.
